Additional Image Processing
7.3.8.3 PCR Parameters Tab
The PCR parameters tab provides the EMS user the following information and set-up
capabilities:
■
Clock Source – You can select one of the following clock sources:
❑
Original PCR
❑
Decoder Clock
❑
Genlock
10
– Use this menu to sync with the incoming signal. The Genlock menu enables
two radio buttons:
• Analog – Analog genlocking supports PAL B/G, NTSC, 720P (50, 59, 60 Hz) and
1080i (50, 59, 60 Hz). The main output must be configured to PAL B/G or NTSC. When
you use an analog clock source you can configure the following:
· Horizontal Delay – The range is 0 – 1728 in 37 ns or 27 MHz ticks. The default is 0 .
· Vertical Delay – The range is -7 – 6. The default is 0 .
· SCH Phase Delay – The range is 0° – 360°. The default is 0 .
• Digital – Digital genlocking supports PAL B/G, NTSC, 720P (50, 59, 60 Hz) and
1080i (50, 59, 60 Hz). The main output must be configured to PAL B/G, NTSC,
720P (50, 59, 60 Hz) or 1080i (50, 59, 60 Hz).
You must select either Analog or Digital . The default is Digital .
■
A/V Sync – You can select one of the following audio/video synchronization parameters:
❑
Off
❑
Frame – Select this parameter to limit the audio/video sync jitter to 1 frame.
❑
5 ms – Select this parameter to limit the audio/video sync jitter to 5 ms when the clock
source is set to Original PCR.
■
A/V Offset Compensation – sets the A/V offset compensation. You can only use this
parameter with the 5 ms parameter. The range is -20 – 20 ms. The default is 0 .
■
Decoding Buffer Delay – sets the delay time for the buffer. Range: 1 – 300 msec. The
default is 100 .
10. Only available with certain hardware configurations, see B.6 Front End Card Features .
